Dual Speed Electric Fan Control Wiring Harness Kit 674-00923, Compatible with Chevy Silverado Avalanche Suburban Tahoe GMC Sierra Yukon, Retrofit Stand Alone Electric Fan Harness

Tried a cheaper version of this kit. Didn't work and would cause a short. Installed this one and worked a lot better. Felt like better quality. Definitely would recommend

I got this as I really liked the breaker/relay mounting arrangement. But once I received it, I realized that they had wired it with 14ga wire. The breakers are 30A, so that's not acceptable (safe). I also didn't like the lengths of some of their wires to position everything exactly where I needed (theirs were too short). So, I ended up re-wiring it all with 10GA wire (for the power connections), and it turned out nice. But only take this path if you happen to have all the correct wire, terminals, crimpers, etc...

Truly impressive! Nice build quality very nice fit! Do it! Way worth the money compared to the 25$ one. I had the cheaper one and it melted, this one looks so much nicer!

I adjusted it by changing how they ran both grounds to one 12ga cable and split it into separate 12ga cables so it’s wired just like the one harness. Now it has been working for few months on my daily drive that sees 110 miles a day.

The media could not be loaded. Quality of the product is pretty good. The installation of it was VERY EASY, it was pretty much plug in and play. For someone that’s not totally mechanically inclined could possibly even do it. The Value for the price is pretty good.I now have both of my fans working on low and high. Product works and does what it should

The media could not be loaded. I bought a competing product for ~$25. It was wired incorrectly and did not work. This did the job and was well worth the cost.

This harness made my fans surge and sent me through a loop. Upgraded ground, upgraded alternator, upgraded alternator wire, upgraded battery, upgraded relays. Save yourself the trouble

price and quality are great i checked out a few different brands and manufacturers and this absolutely is worth the money .. wires were perfect length and fit for my 03 suburban .....
